CHARLES F. FRANZ, BIOHVILLE, MINNESOTA;

COMBINATION SCREEN AND STORM DOOR.

Specification of Letters Patent.

Patented Oct. 9, 1917.

Application filed November 5, 1914. Serial No. 870,588.

To all whom it may concern:

Be it known that I, CHARLES F. FRANZ, a citizen of the United States, residing at Richville, in the county of Ottertail and State of Minnesota, have invented certain iew and useful Improvements in Combinazion Screen and Storm Doors; and I do iereby declare the followi g to be a full, :lear, and exact description f the invention, :uch as will enable others illed in the art Jo which it appertains to ake and use the ame.

This invention relates to doors and more iarticularly to a combined creen and storm loor.

The invention has for ts rimary obact to provide a simple an e cient screen oorwhich may be quickly nd conveniently onverted by the mere insertion of an imerforate panel into an eflicientstorm door.

Another object is the provision of novel nd-eflicient means for re iably and detachbly securing the panel or door covering in osition.

With these and other objects in view, the mention consists in the novel construction, 'rangement and formation of parts as will hereinafter specifically described, claimed id illustrated in the accompanying drawin.which:

iguie 1 represents a front elevation of e combined screen and storm door, partly *oken away.

Fig. 2 represents a transverse sectional ew on the line 2-2 of Fig. 1.

Fig. 3 represents a fragmental longitudi- .l sectional view taken through the upper -rtion of the door on the line 33, and

Fig. 4 represents a fragmental longitudil sectional view taken through the lower rtion of the door on the line 4-4 of Referring to the drawing in detail, wheresimilar reference numerals designate rresponding parts throughout the several we, the numeral 5 indicates the frame of adoor generally, which is preferably proled with a center vertic l mullion 6 and .llion 7. The openings b tween the memf I r I hers of the door frame are covered by a fly screen 8 suitably secured to the door frame.

Vertically and horizontally disposed guides 9 and 10, respectively, are secured adacent the inner edges of the vertical side and bottom members of the door frame and are preferably U-shaped in cross section, as clearly indicated in Figs. 2 and 4, to permit insertion of the imperforate panel or cover 11. Clamping stri s 12 and 13 are secured the vertical mul ion 6 and mullion 7 respectively, by wing nuts and bolts 13 and rmly clamp the screen 8 and panel or cover 11 against the vertical mullion and mullion 7. A clamping bar or strip 14 is secured to the up er horizontal member of the door frame tremities of the vertical uides and reliably clamps the upper edge of the panel or covering 11 against the upper portion of the door frame.

The panel or cover 11 may be constructed of wood or any other suitable material, but by preference a sheet of relatively thick water-proof paper such as is commonly used by builders for temporary roofin is used. An aperture 16 constituting a win ow is formed in the upper portion of the cover or panel 11 and is closed by a transparent insert 17 suitably secured to the inner surface thereof.

During relatively cold weather the door panel or cover 11 is positioned in the guides 9 and and is reliably secured in position on the door frame by the clamping etween the upper exstrips 12, 13 and 14 and the wing nuts and bolts 13, whereas during the warm summer months the clamping strips 12, 13 and 14 are removed, the panel or cover 11 withdrawn from the guides and the clamping strips are replaced to reliablysecure the screen 8 in position upon the door frame.

What I claim is:

A combined screen and storm door comprising a frame having vertical and horizontal mullions, frame, guides located at opposite sides of the frame and extending downwardly from the top thereof and provided with a cona screen mounted upon the necting portion extending across the botmullions and detachnbly securing the said tom of the frame and closing the lower ends cover or anel in the guides.

of the guides, a p:11)nel 0r cfovler fextending Novem er 2nd, 19144 from the top to the ottom 0 t e rame and 1 r 5 slidabiy arranged within the said guides and CHARLES RANA- introduced into the same at the upper ends Signed in our presence:

thereof and clamping bars extending across G. F. Bnooxs,

the top of the frame and along the said 0. G. H-AYHURSL
